KONFIGURASI DNS LINUX SUSE
Seeting DNS Linux Suse 10.2
Contoh Kasus :
Domain : biner.com
IP server : 192.168.254.1
1. Install linux Suse 10.2
Siapkan PC untuk install linux suse, install dengan mode text.
2. Setting IP
yast -> Network Device -> Network Card -> Traditional Method with ifup -> pilih card -> edit -> Statistic Address Setup
-> Ip Address : 192.168.254.1 -> Subnet Mask : 255.255.255.0 -> Next -> Finish
3. Hostname
yast -> Network Service -> DNs and Hostname -> Hostname : server -> Domain Name : biner.com -> Finish
4. Install aplikasi
untuk DNS :
bind
DNS Server
untuk webserver:
apache
yast2-http-server
tool:
mc
5. aktifkan IP forwarding
Yast -> Network Service -> routing
aktifkan : enable IP Forwarding
6. Menjalankan bind

# This is a sample configuration file for the name server BIND 9. It works as
# a caching only name server without modification.
#
# A sample configuration for setting up your own domain can be found in
# /usr/share/doc/packages/bind/sample-config.
#
# A description of all available options can be found in
# /usr/share/doc/packages/bind/misc/options.

# pathenames are relative to the chroot jail.

# should be forwarded. Enable this line and modify the IP address to
# your provider’s name server. Up to three servers may be listed.
#forwarders { 192.0.2.1; 192.0.2.2; };
# Enable the next entry to prefer usage of the name server declared in
# the forwarders section.

# The listen-on record contains a list of local network interfaces to
# listen on. Optionally the port can be specified. Default is to
# listen on all interfaces found on your system. The default port is
# 53.
#listen-on port 53 { 127.0.0.1; };
# The listen-on-v6 record enables or disables listening on IPv6
# interfaces. Allowed values are ‘any’ and ‘none’ or a list of

# the local server and the internet.

# The allow-query record contains a list of networks or IP addresses
# to accept and deny queries from. The default is to allow queries
# from all hosts.

# If notify is set to yes (default), notify messages are sent to other
# name servers when the the zone data is changed. Instead of setting
# a global ‘notify’ statement in the ‘options’ section, a separate
# ‘notify’ can be added to each zone definition.

D. Cek DNS
1. Restart bind
# /etc/init.d/named restart
Shutting down name server BIND done
Starting name server BIND done
(jika masih belum muncul seperti di atas masih salah cek lagi penulisannya )
2. cek host
# host server.biner.com
server.biner.com has address 192.168.254.1
3. cek server
# nslookup server
Server: 127.0.0.1
Address: 127.0.0.1#53
Name: server.biner.com
Address: 192.168.254.1
